OBJECTIVES
Marrow stromal cells are mesenchymal stem cells able to differentiate into cardiomyocytes in vitro. We tested the hypothesis that marrow stromal cells, when implanted into myocardium, can… (More)

BACKGROUND
Damaged skeletal muscle is able to regenerate because of the presence of satellite cells, which are undifferentiated myoblasts. In contrast, destruction of cardiac myocytes is associated… (More)

Bedside percutaneous tracheostomies are increasingly performed. This avoids patient transport to the operating room. Complications of this procedure are largely related to the blind nature of the… (More)

BACKGROUND
We hypothesize that the integrity of the latissimus dorsi muscle graft used to wrap the heart may affect the clinical outcome of patients undergoing dynamic cardiomyoplasty.
METHODS
By… (More)

OBJECTIVE
Because adynamic cardiomyoplasty, or wrapping skeletal muscle around the heart, had been shown to provide a girdling effect and delay progressive ventricular dilatation in heart failure, a… (More)

Myocardium lacks the ability to regenerate following injury. This is in contrast to skeletal muscle (SKM), in which capacity for tissue repair is attributed to the presence of satellite cells. It was… (More)

Although lobectomy is the procedure of preference for patients with peripheral, clinical Stage I bronchogenic carcinomas, wedge resection of the tumor may be a satisfactory alternative in poor-risk… (More)
